On the way back from the Trafford Centre today I looked at the empty plot of land not far along Barton Dock road (heading south east). It has been a bit of a dump for a good few years since the building that stood on the site was pulled down, so I wondered if Merlin could perhaps develop it into some sort of miniature Legoland attraction, or a miniature theme park style area? It's highly unlikely and I've no idea if they'd even be allowed to. It'd also probably cost quite a bit and it's probably too ambitious, but the transport links are all there and there's more than enough parking to support another attraction opening in the area.
The SEALIFE Centre is going just a little further up in Barton Square from where LDC is at the moment (facing the entrance its further up to the right). I don't think we'll see anything too spectacular in terms of leisure attractions from that space you mentioned BigAl, at least not without a massive investment in some decent transport links. As lenient as I feel the council have been with the Trafford Centre in the past, it's simply not sustainable for them to add more large scale attractions at present due to the strain it puts on the M60 at busy period as it is.
I too spotted that piece of land though, although I think it's more likely being redeveloped as part of the work they're doing on Eventcity rather than anything else (I love those new lights!). I have a feeling they're wanting additional car parking closer to the venue in order to bid for some concerts.
